This invention relates to forcing devices, pawl-like members 14:, therev being in this and particularly to a device for forcing instance preferably three of the members 1%, bearings from a vehicle hub. equally divided around the periphery of the An object of this invention is to provide head 15; that is to say, spaced substantially a device by which the bearing may be taken 120 degrees apart. The 'members 14 are 55' from the hub of a Ford car or from other provided with inclined outer faces 16 and motor vehicle cars and to provide a device with shoulders 17 and are carried in chanfor generallyforcing the bearings which is nels 18, an end'of the channel 18 being inofsimple construction, which may be quickly cllned as at 19 to cooperate with the shoulapplied and which is eflicient in operation, der 17 to form a rigld support in holding 60 and which may be manufactured and sold the pawl 14 in a predetermined outward at a cost which will compel its use. pos1t1on,the pawl lt being pivoted upon a lVith the foregoing and other objects-in p1n 20, and being adapted when-in a closed view, I have invented the device illustrated position or when swung into the channel in the accompanying drawings, in wlnch: or slot- 18 to be co-planar with or beneath 6 Figure 1 is a section through a hub prothe plane of thehead and being yieldingly vided with my improved attachment. held outwardly by a spring 21.
